Brass Hose Barb Fitting

This SPEEDAIRE brass fitting connects a 5/8 in hose barb to a 1/2 in male NPT thread for air-powered tool lines. The 90-degree elbow shape routes hose neatly in tight compressor installations. Brass construction resists corrosion from moisture in compressed air systems. Rated for 300 psi working pressure in shop environments.

Replacing Worn or Leaking Barbs

Swap this in when an existing hose barb shows cracks, stripped threads or persistent leaks at the connection. The reusable design allows disassembly and reinstallation without replacing the hose end. Upgrade from a straight barb when routing space demands a right-angle turn at the tool or regulator. The jump is worth it whenever the current fitting restricts airflow or cannot seal at system pressure.

Capacity and Headroom

Comfortably handles standard shop air lines running up to 300 psi with a 5/8 in internal diameter hose. Brass-on-brass threads maintain seal integrity through repeated connect-disconnect cycles. Runs out when the application demands a larger hose bore, a different thread standard or a swivel feature not present on this rigid elbow. Not suited for hydraulic fluid or fuel transfer lines.

Questions about this item

What hose inside diameter fits the 5/8 in barb on this brass fitting?

The barb is sized for 5/8 in inside diameter hose, so push the hose over the beaded end until it seats fully against the shoulder.

How do I install the 1/2 in MNPT end without stripping the brass threads?

Wrap PTFE tape clockwise on the male NPT threads, hand-tighten, then finish with a wrench — overtightening brass NPT threads is the common mistake that causes cracks.

When should I replace this reusable brass elbow fitting?

Replace it if the barb beads show deformation, the brass body has cracks, or the NPT threads no longer seal at 300 psi working pressure.
